Hi Sir ,
Could you help me to know the meaning of the marking code, thanks.
I found the last letter in the third line is different . Would you pls give me your professional advise about the meaing of "D" and "G "? Thx.
The code you are interested in is traceability code used for internal purposes.
For you, as a customer, is important that you have device S9S12ZVL32F0VLF which contains a mask set 0N22G. The mask set defines errata list which can be found at the https://www.nxp.com/docs/en/errata/MSE9S12ZVL_0N22G.pdf
The only we share is 4th and 5th letter in the code (CTXMRD or CTXMRG), It is a date code. In your case yr 2019 wk 44. All other letter are internal use only.
The devices are absolutely the same.
